if you have any doubts, I would be happy to answer. When heated in a microwave, the viscosity decreases and the syrup flows more freely. For example, when syrup is cold it has a high viscosity and can be difficult to pour. The energy of this movement is enough to overcome the forces that bind the molecules together, allowing the liquid to become more fluid and decreasing its viscosity. When a liquid heats up, its molecules become excited and begin to move. Two long tubes are filled with fluids of different viscosities, one with water and the other with glycerin. Always remember, viscosity changes with the change in temperature. Finding viscosity of a liquid by measuring velocity of small balls sinking in the tall tubes, and applying Stoke’s equation. So here Honey has high Viscosity than water. Honey would reach the bottom very slowly, whereas water would be a lot quicker. A way to test for viscosity is the speed at which the substance runs down a slope. For eg: Honey has high viscosity than water. Liquids with high viscosity have more friction in their molecules whic stop or resist them to flow in higher speed unlike water which has a very low viscosity and flows in high speed with very low friction as it's molecules are not tightly packed. It shows the opposition of a liquid to flow (or resistance of a liquid to flow). What is viscosity and its effects on liquid.? Viscosity is a physical property of fluids. Always remember, viscosity changes with the change in temperature. Viscosity is a physical property of fluids.
